Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(5,6,8,11,9,7,10,12)(14,19,21,25)(20,26,27,28);(1,2,3,4)(13,14)(15,20)(16,19)(17,25)(18,21)(22,26)(23,28)(24,27);(5,7,8,12,9,6,10,11)(13,15,17,23,18,24,16,22)(14,20,25,28,21,27,19,26);(6,7)(11,12)(13,16,18,17)(14,19,21,25)(15,22,24,23)(20,26,27,28)
